There was once a prince who wanted to marry a princess. But she must be a real princess, mind you. So he traveled all round the world, seeking such a one, but everywhere something was in the way. Not that there was any lack of princesses, but he could not seem to make out whether they were real princesses; there was always something not quite satisfactory. Therefore, home he came again, quite out of spirits, for he wished so much to marry a real princess.
